## 194. Transpose File
##
## Given a text file file.txt, transpose its content.
##
## You may assume that each row has the same number of columns and each field is separated by the ' ' character.
##
## Example:
##
## If file.txt has the following content:
##
## name age
## alice 21
## ryan 30
##
## Output the following:
##
## name alice ryan
## age 21 30
##
## Read from the file file.txt and print its transposed content to stdout.

{
    for (i = 1; i <= NF; i++) {
        if(NR == 1) {
            s[i] = $i;
        } else {
            s[i] = s[i] " " $i;
        }
    }
}
END {
    for (i = 1; s[i] != ""; i++) {
        print s[i];
    }
